The invention relates to a supramolecular polymer obtained from the reaction of (i) an amine bearing a nitrogen-containing heterocyclic group: imidazolidone, trimethyleneurea or triazine, which is capable of associating by means of hydrogen bonds and (ii) at least one fatty acid monomer comprising at least one reactive function, a dimer of identical or different fatty acids and/or a trimer of identical or different fatty acids, or a derivative of said fatty acid(s) which is selected from a fatty acid ester, and a fatty acid chloride.
摘要:
A polymeric material from the styrene family comprises macromolecular chains grafted by nitrogen-containing heterocyclic groups; wherein the macromolecular chains comprise a polymeric backbone to which a grafted agent is attached by at least one covalent bond, the grafting agent comprises, in a single molecule, one or more associative groups capable of being bound by hydrogen bonds, and one or more reactive groups capable of forming covalent bonds with the polymeric backbone, at least one of the associative groups of the modifier is an imidazolidone heterocyclic ring. The mean number of imidazolidone groups to be inserted into the macromolecular chains is dependent both on the mean mass of said chains and on the final properties to be imparted to the material. Objects such as tubes, films, plates, stiffeners, bottles and containers can be made.

The polymeric material of the invention can be extruded, coextruded, injected, blow-moulded, moulded, overmoulded, calendered or thermoformed. Objects such as tubes, films, plates, stiffenerss, bottles and containers can be made. The polymeric material of the invention can also be blended with other materials such as other polymers, and can thus be modified by elastomeric phases that enhance the impact strength thereof. The polymeric material of the invention can be a component of masterbatches of additives such as pigments and fillers. The present invention further relates to the use of said polymeric material as a compatibilization agent in a composition including, inter alia, at least two polymers belonging to different polymeric classes.”
